Gallery: Porsche’s secret stash

Dieter Landenberger is manager of Porsche's archives and a man who probably knows more about Porsche's history and heritage than the Porsche family themselves. This is fortuitous, as I'm currently in a warehouse containing many curious Porsches, most of which I'm struggling to identify. There is a reason I'm here. Porsche has a museum (if you haven't been and happen to find yourself in Stuttgart, go. It's amazing. Especially the escalator) but the 80 cars there are just the tip of a 500-strong iceberg. All of which have to be stored somewhere.
